Further, the container nozzle 112 is combined with the container cap 140 by means of thread rotation to make for unscrewing or screwing during use. Alternatively, the container nozzle 112 may be combined with the container cap 140 by other common means in the art.

The collapsible container body 130 is connected to the first cap 110 and the second cap 120 respectively in a sealable manner. Preferably, the container body 130 is made of self-leakproof material, PE, PP or TPU for example. These materials may be freely collapsed without damage.

As shown in FIG. 3, the collapsible container body 130 is a membrane cut from any of the foregoing materials. The two lateral ends of the membrane are curled face to face. After their end margins 131 a and 131 b overlap, a cylindrical barrel with a first opening end 132 and a second opening end 133 is formed by means of welding. The first opening end 132 of the barrel is combined with the first cap 110, and the second opening end 133 is combined with the second cap 120.

As shown in FIG. 4, welding points are arranged at location 111 where the first cap 110 contacts the margin of the first opening end of the container body 130 and at location 121 where the second cap 120 contacts the margin of the second opening end of the container body 130 respectively. The container body 130 is fixed and sealed with the first cap 110 and the second cap 120 by means of welding. In this way, a collapsible container 10 may be obtained.

As shown in FIG. 5˜FIG. 7, the first cap 110 and the second cap 120 are coupled with each other through a fastening component after the container body 130 is compressed and collapsed to reduce volume and make for carriage. In an embodiment, the fastening component comprises a buckle 150 arranged on the inner wall of the first cap 110 and a strip-type fastener 160 arranged in a corresponding position on the outer wall of the second cap 120 and matched with the buckle 150, wherein the buckle 150 is designed in an L shape, a buckling position 151 is arranged on the buckle 150 and a corresponding fastening position 161 is arranged on the fastener 160.
